Susan Wojcicki passed away on Friday at the young age of 56 after succumbing to cancer.

Wojcicki was the former CEO of YouTube and left her position at the online video behemoth about a year and a half ago, although her health battle was not known publicly at the time. We wrote about Wojcicki's decision and her nine years at YouTube here.

This is from Wojcicki's husband.

'It is with profound sadness that I share the news of Susan Wojcicki passing. My beloved wife of 26 years and mother to our five children left us today after 2 years of living with non-small cell lung cancer,' Dennis Troper wrote in a Facebook post.

Troper said Wojcicki was 'not just my best friend and partner in life, but a brilliant mind, a loving mother, and a dear friend to many.'

'Her impact on our family and the world was immeasurable. We are heartbroken, but grateful for the time we had with her,' Troper said. 'Please keep our family in your thoughts as we navigate this difficult time.'

Regardless of what you may think of Wojcicki's policies at YouTube, this is a real tragedy for her family and friends and they should remain in our prayers.
